"But I'm not good at anything!" Well, I have good news -- throw enough hours of repetition at it and you can get sort of good at anything. I was the world's shittiest writer when I was an infant. I was only slightly better at 25. But while I was failing miserably at my career, I wrote in my spare time for eight straight years, an article a week, before I ever made real money off it. It took 13 years for me to get good enough to make the New York Times best-seller list. It took me probably 20,000 hours of practice to sand the edges off my sucking.
"Don't like the prospect of pouring all of that time into a skill? Well, I have good news and bad news. The good news is that the sheer act of practicing will help you come out of your shell -- I got through years of tedious office work because I knew that I was learning a unique skill on the side. People quit because it takes too long to see results, because they can't figure out that the process is the result."
